Subject: [PATCH] feat(db): add sqlx migrate feature and renumber migration
 files

- Add 'migrate' feature to sqlx dependency
- Renumber migrations to fix duplicate version numbers (two 014 files)
- Re-sequence migrations 009-012 for continuous ordering
- Add ALTER TABLE ADD COLUMN IF NOT EXISTS baseline for notification
  table to handle existing databases missing newer columns
- Remove deleted IM migration files (009-012) that were superseded
